Evaluation of various products for sediment perimeter barrier
… a best management practice known as a sediment perimeter barrier (SPB) or a sediment retention device is implemented. Several products have been designed for use as SPBs, the most common of which is silt fence. However, many of these products have not been tested for their relative performance …

Boundary Properties for Almost-Minimizers of the Relative Perimeter
… regularity for almost-minimizers of the relative perimeter in A. An almost-minimizer of the relative perimeter in A is a measurable set E that minimizes the perimeter functional P(E;A), roughly speaking the (n-1)-area of the boundary of E in A, among local competitors for E. Important examples of …

'Walk the Perimeter': Stories of Place in the Falkland Islands
Rising to my feet on New Island in the South Atlantic, surrounded by thick tussac grass, a cross section of the landscape enters my mind. There is the sky, the grass and the soil, which is interspersed with thousands of burrows. Each burrow ends in a cavern with a small thin-billed prion chick. I …
